Power supply unit
Characteristic value P
The supply voltage inputs are designed for operation with safety extra-
low voltage. Connect only SELV circuits with voltage restrictions in line
with IEC/EN 60950-1 to the supply voltage connections.
Make sure that the connected supply voltage complies the
requirements of IEEE 802.3af or IEEE 802.3at:
For the use of type-1-powered devices (PoE):
Rated voltage DC: 48 V
Max. voltage range DC: 45 V ... 57 V
For the use of type-2-powered devices (PoE+):
Rated voltage DC: 54 V
Max. voltage range DC: 51 V ... 57 V
Max. PoE power
